摘　　要：通过化学沉积法在TiO_(2)载体上制备三元非贵金属Co-Ni-B催化剂,其中载体TiO_(2)采用水热法合成。实验通过调节化学沉积法制备催化剂的反应时间对样品进行最优选择,进而探究出本实验体系的最佳制备催化剂的反应时间。结果表明:反应时间为7 min所制备的Co-Ni-B/TiO_(2)催化剂在硼氢化钠水解制氢中表现较高活性,其放氢的速率可以达到6298.1 mL·min^(-1)·g^(-1)。The method of chemical deposition was used to prepare a ternary non-noble metal Co-Ni-B catalyst on the basis of TiO_(2)as the carrier.The carrier TiO_(2)was synthesized by hydrothermal method.The experiment adjusted the reaction time of the catalyst prepared by chemical deposition to optimize the sample.And then the best reaction time for preparing the catalyst was explored.The results showed that,the Co-Ni-B/TiO_(2)catalyst prepared with a reaction time of 7 min had high catalytic activity in the process of sodium borohydride hydrolysis to produce hydrogen,and its hydrogen production rate reached 6298.1 mL·min^(-1)·g^(-1).
